Implement a prefetch spill page for SGMAP DMA. This works around a slight
...
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page. This could cause machine checks since the PTE after the last page
would not have the valid bit set.
(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)

Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
...
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
